How Does Period Underwear Work?
Period underwear uses multiple fabric layers to absorb menstrual flow while helping keep the surface dry and comfortable.
1. Moisture-Wicking Top Layer
The top layer helps pull moisture away from the skin to improve comfort during: school, sports, sleep, travel, long wear.
2. Absorbent Core
The absorbent middle layer is designed to lock in menstrual flow while remaining comfortable and flexible.
Different absorbency levels are available for:
- light flow
- medium flow
- heavy flow
- overnight protection

Unlike disposable pads that may shift during movement, reusable period underwear stays securely in place throughout daily activities.
